摘要： A camera system is provided for use in a high-radiation environment includes a camera assembly with a housing enclosing an image sensor for generating a digital signal of a detected image and a first serializer/deserializer (SERDES) for converting the digital signal from the image sensor into a serial bit stream. A transmission medium transmits the serial bit stream to an image processing module located outside of the high-radiation environment where a second SERDES deserializes the serial bit stream to generate a decoded image signal which is processed by an image processor to generate an output at a display device corresponding to the detected image.
